How to switch your energy

Switching energy couldn't be simpler - all you need is your postcode and ideally a recent energy bill, though that's not essential.

Step 1: Compare energy deals currently available

The first step is to compare the energy deals currently available to see how your current deal stacks up. To do this, simply enter your details into our comparison tool above, starting with your postcode because not all energy deals are available nationwide.

Step 2: Choose an energy deal

When you have your results, which should show how much you can expect to spend compared to what you’re currently spending, you can choose a deal that suits you.

Why should I switch energy supplier?

The simple reason is to save money. If you’ve not compared energy prices – never mind switched energy supplier – for a year or more, then it’s highly likely you’re paying far more for your gas and/or electricity deal than you need to. Even if you were on a fixed price deal, you may have been rolled onto your supplier’s standard variable rate tariff when it ended. This tariff can change without notice and is generally the most expensive on offer. If this is the case, you should compare gas and electricity prices to see how much you can save by switching.

That's what Anita Staples did:

"My biggest saving would have to be on my gas and electric bill. I used to be with a supplier that was charging me £115 a month. I compared the deals that were out there and ended up switching energy suppliers which saved me £35 a month and £420 on my energy that year alone. Now I always check to see what’s out there when my renewal is due."

How to get a cheap deal on energy

Energy comparison websites like SaveOnEnergy offer the best way to compare gas and electricity prices – they’re quick, simple to use and provide you with as complete a view of the market as possible. Some energy comparison sites have exclusive deals, while other tariffs may not apply to where you live, so you won’t necessarily see every plan that’s available. You should get a pretty comprehensive overview of what options are likely to be best for you, though – not just by price, but other factors too such as customer service or whether the tariff offers renewable energy.

Most people sign up to fixed deals to get a cheap deal on energy. Unlike standard variable tariffs, the rate charged for each unit of energy is set in stone. Sign up for a fixed price deal, and you protect yourself from unexpected price rises for the duration of your contract. Fixed deals aren’t always the cheapest available, but they’re a good place to start when you switch energy.

And there is a range of smaller suppliers which haven't been around long enough to build up the kind of customer base that the big six have done. These include:

Who are the cheapest energy suppliers?

There’s no single energy supplier which is the cheapest for everyone – it all depends on where you live, your individual needs and your energy usage. You may discover your best option lies with one of the traditional ‘big six’ energy suppliers, or you may find the best deals can be found with one of the smaller companies trying to make waves in a crowded marketplace. Your best tactic is to compare energy plans across a wide range of suppliers to find the one that offers the best gas and electric deals for you.

What do I need to compare energy deals?

When you compare energy deals and switch, you’ll only need two things.

  1. Your postcode - not all energy deals are available throughout the country, so this will help narrow down the deals available in your area.

  2. A recent energy bill - annual savings calculations are made using your current energy spend. Don’t worry if you don’t have a recent bill; the system can make an energy usage estimate based on the number of bedrooms in your property.

Which energy supplier is best for me?

The best energy supplier is different for everyone. It depends what you prioritise in an energy deal. For some people, the cheapest option is always the best. Others might prioritise green energy or a strong customer service record. The type of energy you have is important as well - for instance, if you use both gas and electricity, you might find that it’s best to get each fuel from separate suppliers rather than signing up to a dual fuel deal with a single supplier. 

What kind of tariffs are available to me?

There are several types of energy tariff available to customers. These include:

Renewable tariffs

Renewable energy tariffs, also known as ‘green tariffs’, are plans that use renewable energy where possible to reduce the effects of your energy use on the environment. They typically use 100% renewable electricity from sources including wind and hydroelectricity, plus aim to offset some of the carbon emissions from your gas.

Dual fuel tariffs

Dual fuel energy plans include both gas and electricity, so if you use both forms of energy you can easily receive them from a single supplier instead of having to sign up for two different deals.

Electricity-only tariffs

If you’re one of the four million homes in the UK who exclusively uses electricity to power and heat your home (or if you prefer to get separate gas and electricity tariffs), then an electricity-only tariff is just for you. If you only use electricity, as noted above, you may find it easier to get a renewable electricity deal than those who use gas.

Gas-only tariffs

If you solely heat your home with gas (or you have separate gas and electricity tariffs from separate providers), you should concentrate on gas-only tariffs when comparing energy options.

Fixed price tariffs

These tariffs are among the most popular on the market because they guarantee that the price you pay for each unit of energy you consume is fixed for the duration of your contract. Fixed price tariffs tend to run for 12 or 18 months, so stay aware of when your plan is due to end, as you may be rolled on to the company’s more expensive standard variable tariff.

Business energy tariffs

Business energy tariffs are designed specifically for companies, as opposed to private homes. The energy comparison and sign-up process works slightly differently to personal or domestic energy tariffs.

Gas and electricity FAQs

Can I switch my gas and electricity if I’m renting?

If you rent as opposed to owning your home, then it’s likely you can still take advantage of energy comparison sites and switch your energy supplier as a tenant – particularly if it’s your name on the energy bill. You’ll need to speak to your landlord if they pay the energy bills or include the cost of energy in your rent.

Can I stay with the same gas and electricity supplier?

You’re not obligated to switch to another energy supplier if you find your current supplier offers the best deals. Just remember to check your current deal – if it’s a standard variable tariff, you should be able to switch to a fixed deal with no problems; if you’re on a fixed deal, check there are no penalties for switching.

What information do I need to compare gas and electric prices?

You need the following information to conduct an energy comparison: your current supplier and tariff, your property details, and your energy usage. This will ensure the deals you see show the correct gas and electric prices based on an accurate assessment of your own consumption.

If you then find a deal you want to switch to, you’ll need to supply your own personal and bank details so the new energy company can take over your gas and/or electricity supply.

How long does it take to switch my gas and electricity?

Most energy suppliers are part of the Energy Switch Guarantee, which commits to completing any switch to another supplier without issues within 21 days. You also have a 14-day cooling off period, allowing you to cancel the switch if you change your mind.

What happens if I don’t switch my gas and electricity?

If you decide against switching, you’ll eventually be moved to your supplier’s standard variable tariff, which could see you paying a lot more for your energy than you need to. It’s obviously your choice, but if you want to save money on your energy deal, make sure you know when any fixed deal you might currently be on is coming to an end. This ensures you can switch energy in good time to get the best possible deal without incurring an early exit fee.

Can I switch energy if I have a prepayment meter?

Yes, you can switch energy if you have a prepayment meter, but your deal options might be more limited than if you were on a credit meter. All you need to do is select the prepayment meter option when you’re entering your details to compare available energy deals.

Can I switch energy if I’m in debt to my supplier?

You can switch energy if you're in debt to your supplier, but it depends how long you’ve been in debt and how much you owe. It’s not unusual to owe your supplier a small amount because they will take payments based on estimated usage, so if you’ve used a little more than usual, you’ll owe a little more than you thought. However, if you’ve been in debt for more than 28 days or you owe more than £500 on a prepayment meter, you’ll need to repay what you owe before you can switch energy to a new supplier.

How do I switch energy when I move house?

When you move house, you simply need to inform your current supplier that you’re moving. They’ll either help you close your account or make arrangements for your tariff and supply to be transferred to your new home, as long as the plan is available in that location. If you’re not intending to take your tariff with you, you need to find out who supplies the energy at your new home so you can compare available energy deals and switch.

When is the best time to switch energy?

The best time to switch your energy is immediately if you’re on a standard variable contract, or at any point in the final 49 days of your contract if you’re on a fixed deal. Find out more about timing your energy switch here.

Will the price cap keep my energy bills low?

No, it’s unlikely that the price cap will keep your energy bills low. All the price cap does is limit the amount that providers can charge you per unit of energy, but there’s nothing stopping you from using a lot of energy and being charged more than the level the price cap is at. To get the lowest possible bills, you need to regularly compare and switch your energy. Find out more about the price cap here.
